Just an interesting item I found as I'm attempting to identify when Colosseum tickets from the CoopCulture website for Belvedere and the Arena are released for the remainder of the 2018 year...
These details appear to be changing regularly, but I was able to find the info below in the source code of the website. The text is sitting there, however, it has a property of "display:none". This means that if you were viewing the website the information is NOT posted, but the text has been loaded to the site. I'm not sure if it was shown on a previous date or there is a plan to change the display property in the near future - that's up to whomever is in charge of their website (which, tbh, drives me a bit batty).
The "hidden" text which may or MAY NOT be accurate states,
"OCTOBER – DECEMBER
On Monday 20th August at 9:00 a.m. it will be possible to book tickets with scheduled entrance time for the Colosseum, quarterly availability, for October, November and December 2018. Differently from what it’s now displayed, the items will be: COLOSSEUM TIME ENTRANCE- COLOSSEUM STERN TIME ENTRANCE – COLOSSEUM TICKETS WITH ENTRANCE TIME FOR SCHOOLS
On Monday 20th August at 9:00 a.m. it will be possible to book for the underground and belvedere tours, quarterly availability, for October, November and December 2018. The items will be: UNDERGROUND TIME ENTRANCE and BELVEDERE TIME ENTRANCE.
On Monday 3rd September at 9:00 a.m. it will be possible to book tickets with scheduled entrance time for the Colosseum, monthly availability, for October 2018. The additional availabilities will flow into the items COLOSSEUM TIME ENTRANCE- COLOSSEUM STERN TIME ENTRANCE.
On the same date and time, it will be possible to book for the underground and belvedere tours, monthly availability, for October 2018. The additional availabilities will flow into the items UNDERGROUND TIME ENTRANCE and BELVEDERE TIME ENTRANCE."
I apologize for the capital letters - not my styling choice!
